are supplied to the mold cavity 34 while the pin 36 is in its extended position the pin 36 in the extended position prevents the loose fibers 38 from being deposited in the space within the mold cavity 34 with the pin 36 in its extended position is disposed the pin 36 in its extended position shields the portion of the mold cavity 34 from the deposit of the fibers 38 referring to fig5 the alternative mold 32 is shown with the pin 36 in the refracted position the mold cavity 34 includes the loose fiber throughout except where the void 40 is defined within the loose fibers 38 and above the pin 36 it should be understood that the void 40 may include a limited number of fibers 38 because there is no partition preventing the fibers 38 from being inadvertently deposited within the void referring to fig6 the alternative mold 32 is shown with the mold cavity 34 filled with loose fibers 38 that are now encapsulated in a resin matrix 42 the resin matrix 42 fills the interstitial areas between the loose fibers 38 and also fills the void 40 shown in fig5 the resin 42 in the void 40 comprises the fastener receptacle area 18 shown in fig1 the resin 42 and the void 40 may include some inadvertently deposited fibers 38 however the density of the fibers 38 should be markedly less than.
