Abstract

A process for production of a monolithic article from a web of fibres of oriented polypropylene polymer, comprising the steps of subjecting the web to elevated temperature and pressure sufficient to melt a proportion of the polymer and compact it, and then cooling the compacted web, wherein an accelerated rate of cooling is employed down to 100~C. The process is of particular benefit when the weight average molecular weight (MW) of the fibres is 250,000 or below. The resultant articles have good stiffness and strength, yet with reasonable ductility. Similar articles cooled slowly are brittle.

Claims (17)

1. A process for production of a monolithic article from a web of fibres of oriented polypropylene homopolymer or copolymer, comprising the steps of subjecting the web to elevated temperature and pressure sufficient to melt a proportion of the polymer and compact it, and then cooling the compacted web, wherein an accelerated rate of cooling is employed down to a lower temperature and in which said lower temperature is a predetermined amount below the recrystallisation temperature of the fibres.
2. A process for production of a monolithic article from a web of fibres of oriented polypropylene homopolymer or copolymer, comprising the steps of subjecting the web to elevated temperature and pressure sufficient to melt a proportion of the polymer and compact it, and then cooling the compacted web, wherein an accelerated rate of cooling is employed down to 100°C.
3. A process as claimed in claim 1 or 2 wherein the compacted web is cooled at a mean rate of at least 10°C per minute, down to 100°C.
4. A process as claimed in claim 2 or 3 wherein the compacted web is cooled at a mean rate of at least 30°C per minute, down to 100°C.
5. A process as claimed in any preceding claim wherein the compaction pressure does not exceed 10 MPa.
6. A process as claimed in any preceding claim, wherein the fibres are melt formed fibres.
7. A process as claimed in any preceding claim wherein the weight average molecular weight (MW) of the fibres is in the range 100,000 to 800,000.
8. A process as claimed in claim 7 wherein the weight average molecular weight (MW) of the fibres is in the range 100,000 to 250,000.
9. A process as claimed in claim 8 wherein the weight average molecular weight (M W) of the fibres is in the range 150,000 to 220,000.
10. A monolithic article manufactured by a process as claimed in any preceding claim, having a matrix phase of polymer which was produced by selective melting of the oriented phase during the process and an oriented fibre phase a fraction of which was melted during the process.
11. A monolithic article as claimed in claim 10 wherein the Young's modulus of the matrix phase is at least 0.9 GPa.
12. A monolithic article as claimed in claim 10 or 11 Wherein the failure strength of the matrix phase is at least 20 MPa.
13. A monolithic article as claimed in claim 10, 11 or 12 wherein the failure strain of the matrix phase is at least 5%.
14. A monolithic article as claimed in any of claims 10 to 13 wherein the Young's modulus in the longitudinal direction of the oriented fibre phase is at least 4 GPa.
15. A monolithic article as claimed in any of claims 10 to 14 wherein the failure strength in the longitudinal direction of the oriented fibre phase is at least 250 MPa.
16. A monolithic article as claimed in any of claims 10 to 15 wherein the failure strain in the longitudinal direction of the oriented fibre phase is at least 5%.
17. A process of fabricating a monolithic article comprising polypropylene polymer or copolymer, or a monolithic article thus formed, substantially as hereinbefore described with particular reference to the accompanying examples.
